the wavelength of the sound emitted by a dog is 0.009 m ; what is the frequency of the whistle ? ( use the formula : V= frequency x wavelength

  • science -

    V= 330m/s
    Wavelength= .009m

    Frequency= 330/.009 hz

  • ultrasonic dog? -

    The speed of sound in air varies with temperature. It is 331 m/s at 0 C and 343 m/s at 20 C. The whistle frequency would be 37,000 Hz.

    I doubt if the dog emits the sound, as your question implies. It is the dog whistle that makes the sound.
